ASTM A182 lap flanges are known by a variety of names, including support flanges, loose flanges, loose ring flanges, and van stone flanges.

ASTM A182 Gr F9 flanges are typically designed for applications with high temperature requirements. Alloys used to produce flanges according to this specification include wrought or rolled alloys and several stainless steel grades.

Our ASTM A182 F5 Alloy Steel Blind Flanges are square and can be used to connect pipes of nominal bore size without welding and are suitable for high pressure hydraulic systems.

When connecting these parts, put gasket in the middle of two flanges, then tightening the flange screws, so the two will be connected together tightly.

ASTM A193 Grade B7 is the standard material specification for chromium-molybdenum alloy steel fasteners for high-strength, high-temperature, and special-purpose applications. Grade B7 is a heat treated chromium molybdenum alloy steel with a minimum tensile requirement of 100 ksi, a yield strength of 75 ksi and a maximum hardness of 35 HRC. The ASTM A193 specification covers requirements for chemical composition, mechanical properties, hardness, heat treatment, and recommended nut washers for Class B7 fasteners. ASTM A193 Grade B7 is the broadest specification for fasteners, commonly found in bolts or pipes, pressure vessels, valves, flanges and fittings.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

When moving high-temperature or corrosive media through Chrome Alloy Pipe from one process to the next, flanges capable of withstanding harsh environments are critical

Alloy steel sounds like: steel that contains a specific amount of alloying elements. Generally, alloying elements make steel stronger and more resistant to shock or stress. While the most common alloying elements include nickel, chromium, molybdenum, manganese, silicon and copper, many other alloying elements are also used in the production of steel.

The ASTM A194 specification covers carbon, alloy and stainless steel bolts for high pressure and/or high temperature service.

A335 grade P5c pipe is a low alloy carbon steel (Cr-Mo) self-quenching in air where high hardness and residual stress are required for welding and it is not recommended for direct use in services requiring critical conditions. This situation requires the application of post weld heat treatment (PWHT). If you want to avoid PWHT then you can use preheat (120¡ãC) when soldering A335 grade P5c tubes. PWHT is required if the thickness of ASTM A335/ASME SA335 P5c alloy steel pipe is greater than 13 mm.

Alloy steel is divided into two categories: high-alloy steel and low-alloy steel. Low alloy steel flanges, on the other hand, contain about 0.05 ¨C 0.25% carbon and up to 2.0% manganese.

Blind flanges can also be used to seal a nozzle opening on a pressure vessel.
